## sync-ing a phasor~

Jun 02 2006 | 7:23 am
this is probably a wood for the trees thing, but how do I start a phasor~ from 0. every time I play a note or whatever ? the sync input of the saw~ is not to be found on the phasor~, but that's what I need.
or am I being dense ?
thanks,
stuart

phasor~'s second inlet?

i hang my head in shame BUT
can anyone explain the difference, if there is one, between the phase input of phasor~ and the sync input of saw~, and while we're at it, the difference between phase and duty cycle ?
'd be much obliged

phase is a particular appearance or state in a regularly recurring cycle of changes http://dictionary.reference.com/search?q=phase
duty cycle is the high portion in the cycle of a pulse wave http://www.elexp.com/t_oscill.htm

the tri~ and rect~ objects both have 'duty cycle' inputs, and all three of 'saw', 'rect', and 'tri' have a sync input. It's important to keep aware of this distinction.
duty cycle for 'rect~' changes the relative amount of time that the pulse is up versus down. for 'tri~', at 0.5, you get an isoceles triangle wave, and as you change the duty cycle, the relative amount of time that the wave spends going up versus down changes, so that at a duty cycle 0 or 1 the wave is a saw wave, and between 0. see the manual entry on triangle~.
as far as the difference between the phase input on phasor and the sync input on saw~, one practical (if perhaps obvious) difference is that phasor~ takes a float-only input versus the signal-only input of saw~. taken from saw~ entry in manual: "When the control signal crosses from below 0.5 to above 0.5, the oscillator resets itself." This is equivalent to sending a '0' message to phasor - when phasor receives '0', it resets itself.
So in some ways, the 'phase' inlet of phasor~ is more flexible, but it is subject to command processing timing restrictions, hence can't be used to crate traditional sync effects.
As far as your first question is concerned, if your events are triggered by a command rather than a signal, the sending a '0' to phasor~ would accomplish the task.
